Answer:
y = 25
Step-by-step explanation:
To find slope, we use this expression: 
Since we already know the slope and are trying to figure out a y-value, we can input all of the values we do know in the expression and solve for the missing y.
=4
Simplify the denominator: 
=4
Multiply both sides by 6 to isolate the y - 1: y - 1 = 24
Add 1 to both sides to isolate the y: y = 25
y = 25
Answer:
y = mx + c

Answer:
No
Step-by-step explanation:
Write the ratios of erasers to cost (dropping the dollar sign) as fractions:
(number of erasers)/(price): 2/1 and 10/4
The question is if the ratios 2/1 and 10/4 are equivalent.
2/1 = 2
10/4 = 2.5
A proportion is setting two ratios equal. Here, one ratio equals 2, and one ratio equals 2.5.
Since the ratios are not equivalent, the relation is not proportional.
Given the table:
x f(x)
2 6
7 3
9 5
To determine the coordinate given in the table, we have the following:
f(2) = 6
f(7) = 3
f(9) = 5
From the answer choices, the only coordinate given is:
f(5) = 9
ANSWER:
f(9) = 5
Answer:
$348.75
Step-by-step explanation:
$465 * 25%= 116.25
465-116.25 = $348.75
